The process of protein folding describes the transition by which an unordered polypeptide chain attains its functional native three-dimensional structure. A detailed understanding of the principles which govern the protein folding, such as conformational preferences of amino acid residues, the neighbour residue effect and the solvent effects, remains an important …

The identification and quantification of organic compounds present in the environment is a major area of application in modern analytical chemistry. However, it is still scarcely recognized that, in addition to the chemical identity and concentration of organic compounds, there is more information to be found about their source and …

Mercury (Hg) is one of the most toxic metals. Its toxicity depends on the route of exposure, on its chemical form and the dose to which a person is exposed. The most susceptible population are pregnant women and children. Epidemiological studies suggest neuropsychological dysfunctions in children who were prenatally exposed …

Sodium niobate (NaNbO3) is the end member of several alkaline niobate-based solid solutions, which represent an important group of environment-friendly lead-free piezoceramics. Even though alkaline niobates are of considerable technological importance, problems in obtaining high densities and a fine-grained microstructure are still reported and not much is known about the …

The thesis addresses the development of novel knowledge discovery scenarios in a modern data mining platform by utilising principles of service-oriented architecture with web services, interactive scientific workflows, knowledge discovery ontologies and automated construction of data mining workflows. We present the developed Orange4WS platform which upgrades Orange, a mature open-source …

Radon (222Rn, half-life 3.82 days) is a natural radioactive noble gas which originates from the radioactive decay of radium (226Ra) in the Earth's crust. It is a known hazard to humans, due to its radioactivity. Moreover, radon can also be used as a versatile tool in geophysical research. In order …

The aim of the present thesis was to examine the effect of normobaric hypoxic confinement on selected metabolic responses. This was investigated in two separate studies: Study I investigated the effect of normobaric hypoxia, as frequently used by athletes for altitude training, on metabolism. The metabolic responses were assessed in …

The aging of bone tissue, bone defects that form during the removal of cysts, tumours, genetic defects and other bone‐tissue‐related diseases, together with demands for a better quality of life, mean a requirement for materials, artificial or autogenous, that will have a long functionality and survivability under the body’s environmental …

Heterogeneous reactions of trifluoromethane CHF3 with solid xerogel oxides, alkali hydroxides and carbonates were investigated under static and dynamic conditions and at moderate temperatures. In all cases, main reaction is fluorination characterised by a complete decomposition (mineralisation) of the fluorinating agent, CHF3, and the formation of the solid metal fluorides. …

The KNN solid solution was prepared from pre-synthesized binary compounds of, sodium and potassium niobate in a 1/1 molar ratio. The KNG sintering aid was prepared by homogenizing the pre-reacted binary mixtures of alkaline reagents and germanium oxide with the Na/Ge = 1/1 and K/Ge = 1/1 molar ratios. The …
